IMPROVEMENT CHIMNEY COLLARS.

TO ALL WHOM IT MAY CONCERN:

Be it knownl that I, JOHN STOKELY, of Hiram, in the county of Portage, andState of Ohio, -have invented a new and improved Collar to. Prevent Leakage around Chimneys;- and do hereby declare the following to lic' a v full, clear, and exact description of Athe same', reference being had'to the accompanying drawings, in which-d Figure l is a perspective. view of a-chimney with my collar applied.. Figure 2is a perspective view of the various parts of my collar, detached. Figure 3 represents a modificationV by which the laps may be dispensed with. Figure 4 representsthe method of laying 'shingles in connection with my collar. There is no more fruitful source of trouble, annoyance, and damage connected with. the subject of housebuilding than leaky chimneys. Water will find an entrance around a chimney sometimes when thentmost care has been used in applying the common modes of prevention. My'invention is designed to obviate these diis oulties perfectly and without material increase of cost, while the decrease of trouble and expense of tting will be considerable.

That others may understand the construction and application of my invention, I will particularly describe it. I prefer to make my device of sheet metal, tin being the materiall ordinarily used, though zinc or copper Wouldbe preferable, as being much more durable. The part which is most .diiiicult to. secnr'e against the ihgress of water is that against which the water runsin descending from the higher part of the roof. I place upon' that portion the section A, which in one continuons picce'passes across the entire width-.of the chimney and for a space Varound the end. The section A is composed of the bed-plate a andv the perpendicular wall b, made in one part Without'any seam at` the bend. The angle included between a and b should be exactly equal to the angle included between the chimney and roof, the ends of the section turned `around the two corners of the chimney, so as to leaver no'seam or open joint. When'the shingles are laid they overlap the bed a not, however, coming quite down to the ange or wall b Expansion and contraction by changes of temperature cause the ordinary metallic fittings to become loose, displaced, and 'broken but there can be no such trouble with my fitting, because it will only be fastened atone edge-'and may be freeto move as it expands or contracts at the other. This is acetmiplished by leaving the top of the wall bl unfastened, and covering the joint between it and the chimney by the lap B, one edge of. which is inserted between courses of the brick, while the other hangsover and covers the upper edge of b. At the side or edge of the' chimney shorter angle-pieces like C are used; they areisomctvhat'longer than the brick, and the edge of the upright parts is cut angling,

`so that when placed on the inclined surface of the roof the upper edge ofthe perpendicular portion will be level and extend upwards nearlyto the joint between two courses-of the bricks.` Anangle-piece like B is used in connection with this piece, the edge-toward theolpper part of thereof is inserted beneath A, so that the water will shed from one to the other. In length-,the Ipieces C are a little greater than the length of a brick, so that the necessary oifsets from one to'ano'ther may occur ivith the regularity of thebrick-Work; though further than this it is not necessary to observe any particular dimensions. The section D is like A, except that the perpendicular portion is set upon the bed ata different angle, but still so aste conform to the angle betiveen theV chimney and roof. The bed-plate of the section D lies on top of the shingles of the roof below the chimney, instead of extending up under them, as A does. This is to'require the water which runs down the chimney to shed from the collar on to the shingles on that side. The shingles at the side or end past the short sections are laid in the usual manner, the only change being in omitting that portion opposite the chimney on its lower side, which is commonly'laid close up and incontact.

It may be sometimes desirable to construct these collars of cast metal, or it may Asometimes be deemed desirable to make the edge which is inserted between the bricks of the chimney of the same piece asithe hed and the walls. If desired', all of the joints between thesections A C and D may be solderedso as to-surroun'd the chimneywith a jcintless collar.

Having described my invention, what I-claiin as new, and desire to secure by LettersPatent, is- The chimney collar constructed of the sections C and D,"s '\stantially as setfforth. Y The lap B, for the purpose of covering the loose edgesof the L .imney collar, substantially :as sot forth.v
